Novel precipitated silica particulates, well suited for conditioning/sorbing a wide variety of liquid active agents thereon, e.g., the vitamins, have (i) a BET surface area of at least 170 m 2 /g; (ii) an oil absorption (DOP) ranging from 220 to 300 ml/g; (iii) a fill density in the packed state of at least 0.29; (iv) a mean particle diameter ranging from 80 to 150 μm; and (v) a maximum grain size distribution index of 0.70. |
